Alice J. Hovorka 《Development in Practice》2006,16(1):51-61
This paper considers the role of urban agriculture in addressing the practical and strategic needs of African women, and assesses the gender implications of embracing urban agriculture as a development intervention strategy. Empirical evidence from Botswana and Zimbabwe points to the multi-faceted role of urban agriculture whereby some women use this activity to support their households on a daily basis, and others use it as an avenue for social and economic empowerment over the longer term. In order to benefit rather than burden women, the promotion and support of urban agriculture must take on an emancipatory agenda, which supports individual, practical and strategic goals, and ultimately challenges the structural conditions that give rise to women's involvement in the activity in the first place. 相似文献

This paper demonstrates the applicability of two empirical techniques—the Heckman two-stage switching regression and the event study methodology—for evaluating regulatory or legislative change relating to companies and in particular to the regulation of company reporting. These techniques measure the impact of regulatory changes once they have happened. They could be used in practice if regulatory changes were subject to a review procedure. The availability of these relatively sophisticated techniques should encourage the quantitative analysis of regulatory changes. Comparisons of effects across member states of the European Union would be interesting but would obviously need care. 相似文献

Temporary migration in Shanghai and Beijing 总被引:1,自引:0,他引:1
In a number of developing countries, temporary migration plays a key role in the labor market. In China, where permanent migration
is carefully controlled, movement without an official change in household registration (temporary migration) is relatively
unrestricted. It has increased dramatically since the economic reforms introduced in 1979. Using data from surveys in Shanghai
and Beijing, this article focuses on the sociodemographic characteristics of temporary migrants in relation to their reasons
for moving and the duration of their stay at destination. Many temporary migrants come to these cities in search of work;
however, many others move for noneconomic reasons associated with family reunion and retirement. Moreover, the distinctive
socioeconomic features of Shanghai and Beijing also influence the characteristics of temporary migrants and their reasons
for coming to the cities.

As students transition into middle school they must successfully negotiate a new, larger peer context to attain or maintain
high social standing. The goal of this study was to examine the extent to which the maintenance, attainment, and loss of a
cool status over the course of the sixth grade is associated with student and classroom levels of physical, verbal, and relational
aggression. To address this goal, we studied a sample of 1985 (55% girls) ethnically diverse adolescents from 99 sixth grade
classrooms in the United States. Attaining a cool status at any point across the school year was associated with stronger
aggressive reputations. Additionally, classroom norms for aggressive behavior moderated the association between changes in
aggression over the school year and the stability of coolness such that students who maintained their coolness across the
school year showed greater increases in their verbally aggressive reputations from fall to spring when they were in classrooms
with higher levels of aggression. The findings illustrate the importance of fitting in with social norms for maintaining a
high social status among a new set of peers in middle school. 相似文献
